1、 Original screen
Original screen refers to a screen produced by a mobile phone manufacturer that is identical to the original screen of the phone. The advantage of this screen is its superior quality and good compatibility with other parts of the phone, ensuring the best display effect and user experience. However, the price of original screens is usually higher due to their production costs and strict quality control. If your phone is still under warranty or you have high demands for screen quality, choosing an original screen is a good choice.

2、 OEM Screen
OEM (Original Equipment Manufacturer) screens are screens produced by partners of mobile phone manufacturers, with similar quality to original screens but usually at a more affordable price. The production process of OEM screens also follows strict standards, so their display effect and service life can be guaranteed. If your budget is limited but you want to get a user experience close to the original screen, then OEM screens are a cost-effective choice.
3、 Compatible with screens
Compatible screens are screens produced by third-party manufacturers, designed to be compatible with multiple phone models. The price of this type of screen is usually lower, but the quality and display effect may vary depending on the manufacturer. When choosing a compatible screen, it is recommended to carefully compare products from different brands and models to ensure that they meet your usage needs. Although screen compatibility may pose certain risks, it is still a viable option if you do not have high requirements for your phone screen or have a very limited budget.

4、 Press fit screenPress fit screen is a type of screen that combines a display screen and a touch screen. The advantage of this screen is that it is reasonably priced, and the display effect and user experience are relatively good. However, the compatibility and stability of laminated screens may not be as good as original or OEM screens, so careful consideration is needed when choosing. If your phone model is relatively rare, or if you do not have high requirements for the display effect and stability of the screen, then pressing the screen may be a suitable choice.
When choosing a mobile phone screen, in addition to considering the screen type and price, it is also necessary to consider the convenience of installation and maintenance. If you do not have the relevant technical knowledge, it is recommended to seek the help of professionals to ensure a smooth screen replacement process.

The difference between the two



1. Thickness: LCD screens are thick and hard, and cannot be bent; OLED screens can be bent, making them softer and thinner. From a structural perspective, AMOLED thickness can be nearly 30% thinner than LCD.





2. Price: Due to the mature technology of LCD, LCD is cheaper in terms of price.



3. Service life: LCD screens use inorganic materials, while OLED screens use organic materials. OLED screens have a shorter service life than LCD screens.



4. Color expression: LCD emits light through backlight refraction, so when displaying black, there may be light leakage and whitening around the screen, making black more similar to gray. OLED can express colors through self emission, resulting in a more vivid and full display effect, but there is a risk of screen burn-in.

5. Energy consumption: The luminous principle of LCD is that the color filter film will cause a decrease in light efficiency. Some analyses suggest that the utilization rate of LCD for backlight brightness will not exceed 15%, and 85% of energy is wasted. Therefore, OLED is more energy-efficient than LCD.



LCD is never a slave



OLED screens are often referred to as "blind screens" due to the issue of screen flicker. When adjusting screen brightness, OLED screens use PWM dimming, which is commonly understood as turning on and off every second to control brightness. The brightness is adjusted by the proportion of screen on/off time within the interval.



As long as I light up and turn off quickly enough, my brain cannot feel that I am rapidly switching between light and light states. For some people who are sensitive to screen flicker, PWM dimming is particularly unfriendly to their eyes at low brightness, especially at night, which is why some people may feel obvious eye pain and soreness when using their phones at night.



However, many manufacturers later introduced DC modulation to solve the problem of screen flicker, but with it came the problems of screen burn-in and uneven brightness.



LCD enthusiasts are shouting: LCD will never be enslaved, because of the fatal problem of OLED screen flicker.

future trends



Although OLED has screen flicker issues, in daily use, the human eye cannot clearly perceive it. Only those who are very sensitive to screen flicker will truly feel discomfort.



OLED with greater power than excess has more advantages, such as better contrast, better black performance, wider color gamut, lighter, thinner, bendable, and so on. That's why mainstream flagship phones now choose OLED screens.

In the future, the development trend of mobile phones will also move towards full screen, curved/foldable screens, and under screen fingerprint and under screen cameras, and the position of OLED will not be shaken. LCD screens will be more commonly used in mid to low end smartphones due to their low cost and mature technology.



So, whether to choose LCD screen or OLED screen, Haoge has summarized their respective advantages and disadvantages for everyone. If you are particularly sensitive to screen flicker, it is recommended to choose LCD. In addition, choosing OLED screen can bring a better visual experience.

011. Analysis of Mobile Screen Technology
1.1 Overview of LCD and OLED
LCD relies on external light sources, while OLED can emit light on its own; The two principles are fundamentally different.
1.2 LCD Screen Technology
LCD screen, also known as Liquid Crystal Display, has become a mature technology after a long period of development and is widely used in various types of mobile phone screens. At present, screen technologies such as TFT, IPS, and SLCD can all be classified as LCD screens. Among them, TFT, as a general term for LCD panels, was once the mainstream of early LCD screens. Although its display effect was mediocre, its cost was low, so it was still adopted by many low-end models.IPS screens, often referred to as "SuperTFT" in the industry, are an upgraded form of LCD screens that essentially still belong to the category of TFT screens. Compared to ordinary TFT screens, IPS screens have a more transparent display effect, bright colors, and a wider viewing angle, reportedly even reaching a viewing angle range of nearly 180 °. SLCD, also known as "Super LCD", belongs to a higher level of LCD screen technology, and its excellent display effect and good color reproduction ability have won widespread praise.
1.3 OLED Display Technology
Compared with LCD screens, the biggest feature of OLED screens is the self luminous display technology of pixels, which makes OLED screens more outstanding in display effects and become the mainstream direction of future screen technology development. At present, AMOLED screens dominate the OLED field, and Samsung, as a leader in mastering core technologies, has achieved increasingly accurate color reproduction in its products, with significant improvements in color cast compared to earlier products. Super AMOLED， As an important product of Samsung in the OLED display market, it is widely praised for its high color saturation and vivid display effects, especially in terms of color performance. Samsung's Super AMOLED screen is considered a leader in the industry.
1.4 [Introduction to 120Hz Flow Rate Screen]
Recently, mobile phone manufacturers have launched 120Hz streaming screens, which brings us a brand new visual experience through technological innovation. The flow rate screen, with its high refresh rate of 120Hz, significantly surpasses the refresh rate of traditional 60Hz mobile phone screens. In fact, the refresh rate of 120Hz flow rate screens has been improved, and optimized circuit components have been used to achieve higher screen refresh rates.

In fact, the perception ability of the human eye is often misled. For example, the common 24FPS frame rate in movies, which plays 24 frames per second, sacrifices 1/24 of a second of motion detail despite the use of motion blur technology to make the images appear coherent. This trade-off may be acceptable for movies, but in games, each frame is a static image rendered in real-time. If it is still presented at 24 frames per second, it will result in disjointed actions. The high refresh rate of the flow screen helps to improve the performance of dynamic images, bringing users a smoother visual experience.

Overall, mobile screen technology is developing towards higher refresh rates and better display effects. LCD occupies a place in the market with its mature technology and diversity, while OLED is gradually becoming mainstream with its excellent display effects and self luminous advantages. With the continuous innovation of technology, future mobile phone screens will definitely bring us more surprises and better user experience
